The Smart Meter Texas website was built by a consortium of electric transmission and distribution utilties, including CenterPoint Energy, Oncor, and American Electric Power, to give customers with smart meters in the service territories of these utilities more control over their electricity use.

Consumers can register at www.SmartMeterTexas.com to access detailed views of their electric usage history in 13-month, 30-day, or 24-hour snapshots down to 15-minute intervals including usage data up two days previous.

The Smart Meter Texas portal also allows retail electric providers (REPs) to access their smart meter customers' usage information to support retail offerings such as energy analysis tools, time-of-use rates, and pre-paid service. Through the portal, REPs can also connect Home Area Network devices to smart meters to help consumers better manage their electricity use by remotely controlling smart electric appliances and thermostats, which are under development by a number of manufacturers.
